Like the title says, if you want to upvote something on KBin, you should use the Boost link, not the upvote button (Why? Don’t know…)
The upvote button doesn’t seem to do much, but Boost accomplishes what Reddit’s upvote did. So if you’re looking to encourage a post, use the Boost link.
There’s several of us now with kbin installed locally and a decent dev chat channel that’s pretty busy. I think so the end it’s still him physically marking PRs as approved and merging it in / deploying, but at least there’s a few contributors now :)
